                                                      TcTpmException

Parameters:

dest - The destination where the byte stream is written to.

antiReplay - Arbitrary data

keyInfo - Information about key to be created, this includes all algorithm parameters

generateReset - If TRUE use TPM RNG to generate EKreset. If FALSE use the passed value inputEKreset

inputEKreset - The authorization value to be usedwith TPM_RevokeTrust if generateReset==FALSE, else the parameter is present but ignored

Returns:

The returned Object[] holds the following elements:

• 0 ... TPM return code (Long)
• 1 ... The public endorsement key (TcTpmPubkey)
• 2 ... Hash of pubEndorsementKey and antiReplay (TcTpmDigest)
• 3 ... The AuthData value to use TPM_RevokeTrust (TcTpmNonce)

Throws:

TcTpmException - This exception indicates that a TPM error has occurred. The specific error code id held by the exception.

TpmRevokeTrust

public static java.lang.Object[] TpmRevokeTrust(TcIStreamDest dest,
                                                TcTpmNonce EKReset)
                                         throws TcTddlException,
                                                TcTpmException

Parameters:

dest - The destination where the byte stream is written to.

EKReset - The value that will be matched toEK Reset

Returns:

The returned Object[] holds the following elements:

• 0 ... TPM return code (Long)

Throws:

TcTpmException - This exception indicates that a TPM error has occurred. The specific error code id held by the exception.

TpmReadPubek

public static java.lang.Object[] TpmReadPubek(TcIStreamDest dest,
                                              TcTpmNonce antiReplay)
                                       throws TcTddlException,
                                              TcTpmException

Return the endorsement key public portion. This value should have controls placed upon access, as it is a privacy sensitive value. The readPubek flag is set to FALSE by TPM_TakeOwnership and set to TRUE by TPM_OwnerClear, thus mirroring if a TPM Owner is present.

Parameters:

dest - The destination where the byte stream is written to.

antiReplay - Arbitrary data

Returns:

The returned Object[] holds the following elements:

• 0 ... TPM return code (Long)
• 1 ... The public endorsement key (TcTpmPubkey)
• 2 ... Hash of pubEndorsementKey and antiReplay (TcTpmDigest)

Throws:

TcTpmException - This exception indicates that a TPM error has occurred. The specific error code id held by the exception.

Parameters:

dest - The destination where the byte stream is written to.

inAuth1 - Authorization values for first authorization session.

keyHandle - Handle for either PUBEK or SRK

Returns:

The returned Object[] holds the following elements:

• 0 ... TPM return code (Long)
• 1 ... outgoing authorization for session containing new nonceEven (TcTpmAuth)
• 2 ... The public portion of the requested key (TcTpmPubkey)

Throws:
